What will be the features in Future Apple Watch??

Apple Watch's Digital Crown as a joystick

The fact that the digital crown of a future Apple Watch could be able to be manipulated in multiple directions to act as a different kind of input device was established publicly in 2018. While Apple mentions a joystick once, it's never repeated.

the strap automatically tightens when running a specific health-monitoring app.

This would push the Watch up against the wearer's skin, ensuring a good contact for taking medical data, like a heart rate or ECG. We wonder if this would also help Apple record more data, not yet captured by current Watches. Glucose monitoring has long been a rumored future feature of Apple's wearable.
